While at Multnomah Falls we were able to view across to the field used for the baseball scene. I found information about the area today.  Its call The Shire.  Owned by University of Oregon.  Designed by John Yeon. I came across this article about it and that they are doing tours of the area this summer.  This area is fenced and is not usually accessible.

In October 1995 the University of Oregon announced the establishment of a nationally-significant center – The Shire: The John Yeon Preserve for Landscape Studies.  The Shire is a unique landscape, sensitively designed as a private park in the heart of the scenic Columbia River Gorge.
